Many knee conditions can be treated with 'keyhole surgery'. A fibreoptic camera is introduced into the knee via a small 1cm incision allowing inside of the joint to be visualised. Further incisions are then made to allow other instruments to be passed into the knee to do the procedure required.
The advantage of arthroscopic surgery is a quicker recovery time. Often a better view is attained of various parts of the knee than at open surgery. Usually procedures are done as a 'day case'.
